Configuration for checking the clamping force of a coupling configuration for a transport assembly in a cableway system

Abstract

A configuration for checking the clamping force to which the supporting and haulage cable is subjected by the coupling configuration for a transport assembly of a cableway system. The coupling configuration has a clamping lever which is subjected to the action of a spring-energy storage device and on which is mounted an actuating roller which rolls along a running surface of a guide rail. The running surface is formed with an elastically deformable region which is assigned a measuring configuration with which it is possible to measure the deformation of the running surface on account of the compressive force which is produced by the spring-energy storage device, acts on the guide surface via the actuating roller and corresponds to the clamping force. In this case, the measuring configuration is formed by at least two measuring units that function in different ways.
